In a nutshell, Overdrive WKF is a form which takes place everytime he gets extremely pressured or damaged, this could happen for a delay though, and the transformation can take place even when WKF is knocked out or paralyzed, completely removing the effects and bringing him back into battle. This however will result in WKF blacking out for an hour after the fight ends, in rare cases, he is still able to be in that form, however, this form makes him hostile to nearly anyone, only after defeating the person that triggered this form.
